11 Claims, 12 Drawing Figures PMENTEL DEC 3!!!" IEIGA- PATENTEL BEE sum 20F 2 'ZFIGJU DISPENSER WITH NOZZLE CUT-OFF Dispensers of the type herein disclosed are readily available, have been known for many years, and in most cases include a cartridge which is simply a cylindrical container body having opposite closed ends which are generally readily removable. The ends are removed and positioned in a dispensing gun which generally includes a piston, a piston rod which has ratchet teeth, and a pivoted trigger associated with the frame for moving the piston by progressively engaging the ratchet teeth of the piston rod. The frame at the end opposite the handle of the dispenser frame generally includes a conical nozzle as an integral part thereof through which the material is dispensed during, for example, a caulking operation.

While such conventional dispensers have been known for many years most if not all suffer from a primary disadvantage, namely, the fact that the cartridge" is not provided with suitable means for cutting off or shutting off the flow of the material after the termination of a dispensing operation. In many cases the material of the cartridge is not completely depleted after a particular job has been done and the dispensable material which is in the cartridge is subject to deleterious effects of air, moisture and contamination. However, in keeping with this invention the cartridge includes a nozzle which can be rotated to close off the interior of the cartridge to atmosphere hence avoiding all disadvantages of known conventional dispensers of this type.

In view of the foregoing it is a primary object of this invention to provide a novel dispenser and more particularly a dispenser cartridge which includes a container body closed at opposite ends, one of which is openable for the receipt of a piston or similar motive force and an opposite end which is closed by a rotatable nozzle which preferably includes an aperture offset from an aperture of a closure of the container body such that upon rotation of the nozzle relative to the closure between dispensing and nondispensing positions the apertures are respectively aligned and opened and misaligned and closed.

A further object of this invention is to provide a novel dispenser of the type aforementioned wherein abutment means are provided between the nozzle and closure for contacting each other at the dispensing and nondispensing positions thereby assuring respective aperture-aperture registration and non-registration.

Still another object of this invention is to provide a novel dispenser wherein the closure includes a wall rebent upon itself to define a radially inwardly opening channel captively though rotatably receiving a peripheral portion of a wall of the nozzle to maintain the nozzle and container body in assembled relationship.

Yet another object of this invention is to provide a novel dispenser of the type hereinbefore set forth wherein a second closure is provided having an opening therein, the nozzle projects through the opening, and a peripheral portion of a wall of the nozzle is captively though rotatably sandwiched between the firstmentioned and second closures.

Yet another object of this invention is to provide a novel dispenser wherein the aperture of the closure opens in a radial direction and the nozzle aperture is an axial passage radially outboard of the closure aperture.

A further object of this invention is to provide a novel dispenser constructed in the manner hereinbefore set forth wherein the closure includes a central blind ended embossment and the closure aperture is in a peripheral wall portion of the embossment.

Stillanother object of this invention is to provide a dispenser of the type set forth wherein a dispensing aperture is formed to open radially through the nozzle wall and the closure is provided with a generally annular recessed wall for closing the dispensing aperture in the nondispensing position of the dispenser components.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claimed subject matter, and the several views illustrated in the accompanying drawings.

IN THE DRAWINGS:

FIG. 1 is a side elevational view of a dispenser or dispenser mechanism constructed in accordance with this invention and discloses a dispenser or dispenser cartridge associated therewith having a rotatable nozzle for shutting or cutting off material flow.

FIG. 2 is an enlarged sectional view taken generally along the line 22 of FIG. 1, and illustrates the manner in which the nozzle is positioned relative to an aperture of a closure associated with a cartridge during the dispensing of material therefrom.

FIG. 3 is an axial sectional view through the dispenser or cartridge and illustrates the manner in which a wall portion of the nozzle overlies the closure aperture to preclude the dispensing of material from the dispenser or container body.

FIG. 5 is a fragmentary perspective view of the dispenser of FIGS. 1-4 and merely indicates the manner in which the. exterior of the dispenser or cartridge body may be identified to indicate closed and open positions thereof.

FIG. 6 is a fragmentary axial sectional view taken through another embodiment of this invention similar to FIG. 3, and illustrates the manner in which a closure of the container body is rebent upon itself to form an annularly radially inwardly opening channel which captively but rotatably houses a wall portion of the nozzle.

FIG. 7 is a fragmentary axial sectional view of another embodiment of this invention similar to FIGS. 3 and 6, and illustrates the manner in which a nozzle is positioned relative to a closure of the container body during a dispensing operation. I

FIG. 8 is a fragmentary sectional view taken generally along the line 88 of FIG. 7 and more clearly illustrates the relative positions of the nozzle and container body closure during the dispensing position to permit the passage of material to atmosphere.

FIG. 9 is a fragmentary sectional view similar to FIG. 8 but illustrates the relative positions of the nozzle and container body closure in a nondispensing position at which a generally annular wall portion of the container body closure closes a radial aperture of the nozzle.

, FIG. is a fragmentary axial sectional view of the nozzle and an associated closure in the dispensing position thereof.

FIG. 1 1 is a front elevational view of the dispenser of FIG. 10 looking from left-to-right, and particularly illustrates the configuration of the dispensing nozzle.

FIG. 12 is a sectional view taken generally along the line l2-12 of FIG. 10 and more clearly illustrates details of the closure, its radially opening apertures, and axial passages of the nozzle associated therewith in the dispensing position.

Reference is first made to FIG. 1 of the drawings which illustrates a dispensing mechanism generally designated by the reference numeral 10 which includes a frame (unnumbered) having a partially circular wall 11 at a forwardmost end and a circular wall 12 at an end remote therefrom with the walls 11, 12 being joined by an upwardly opening generally cylindrical wall 13. The wall 11 is provided with an upwardly opening generally U-shaped slot 14 and between the latter and the wall 12 may be positioned a dispenser or cartridge 15 forming one embodiment of the subject matter of this invention. In addition to the components of the dispensing mechanism 10 heretofore described the same also includes a conventional handle 16, a trigger mechanism 17, a piston rod 18, a piston 19 associated therewith, and a plurality of rack teeth 180. As the trigger 17 is repetitiously pulled toward the handle 16 and released, the piston rod 18 moves leftward whereupon the piston 19 moves a severed end closure 20 of the dispenser 15 leftward causing material (not shown) within the dispenser 15 to advance into and through a nozzle, generally designated by the reference numeral 21. The nozzle 21 is preferably constructed of plastic material and includes a closed tip 22 which may be suitably severed to form a dispensing opening. The nozzle 21 has an axis (unnumbered) coincident to the axis (also unnumbered) of the body 15 and preferably though not necessarily tapers in a converging manner from right-to-left as viewed in FIG. 3. An opening or aperture 23 is formed in a wall 24 of the nozzle 21 with the opening 23 being radially offset from the nozzle and dispenser axes. A wall portion 25 of the wall 24 is also in part radially offset from the nozzle and dispenser body axes. Preferably a peripheral portion (unnumbered) of the nozzle 21 in cludes abutment means in the form of a pair of hookshaped elements 26, 27 (FIG. 4) which cooperate with axially directed abutments 28, 29 of a closure 31 having a peripheral skirt 32 and a generally circular end wall 33 apertured at 34, it being noted that the aperture 34 is likewise offset from the axes of the nozzle 21 and the dispenser l5. Projecting axially from the wall 33 are the pair of abutments 28, 29, in the manner best illustrated in FIG. 3. Another closure 35 includes a generally circular aperture or opening 36 through which projects the nozzle 21 such that the wall 24 thereof is captively though rotationally sandwiched between a wall 37 of the closure 35 and the wall 33 of the closure 31. Preferably the outer periphery 38 of the closure 37 is crimped to secure the components in the relationship best illustrated in FIG. 3. Preferably the internal diameter (unnumbered) of the dispenser 15 is slightly smaller than the exterior periphery of the skirt 32 and during the crimping of the periphery 38 a slight compression of the dispenser material takes place resulting in the captive assembly of the closure 33 in the manner readily apparent in FIG. 3.

After the tip 22 has been severed and removed the cartridge or dispenser 15 is inserted in the dispenser mechanism 10 in the manner best illustrated in FIG. 1 with the nozzle 21 projecting outwardly through the generally U-shaped slot 14. With the nozzle 21 positioned as shown in FIG. 2 the apertures 23, 34 are aligned and upon the continued squeezing of the trigger 17 material will be dispensed under the influence of the piston 19 through the nozzle 21 in a right-to-left direction as viewed in FIGS. 1 and 3. Alignment between the apertures 23, 34 is assured due to the abutment be tween the elements 2629. After the completion of a dispensing operation it is desirable to shut off or cut off the interior of the cartridge 15 to atmosphere and hence the nozzle is rotated in the direction of the unnumbered headed arrow illustrated in FIG. 2 until the position of the nozzle 21 relative to the closure 33 of FIG. 4 is reached at which point the wall portion 25 overlies the aperture 34 and precludes further dispensing of material. Rotation of the nozzle in the direction of the unnumbered solid headed arrow in FIG. 4 will result in the components reaching the dispensing position of FIG. 2.

Reference is now made to FIG. 5 which illustrates the manner in which a portion of the wall 37 of the closure 35 of the cartridge 15 can be raised to form a wall 40 upon which is imprinted the letters C and O with the nozzle being provided with a suitable mark or like indicia 41. When the mark 41 is aligned with the letter C this is an indication of the closed condition of the dispenser 15, as shown in FIG. 4, whereas alignment between the mark 41 and the letter O indicates the open condition of FIG. 2.

Reference is now made to the dispenser or cartridge of FIG. 6 which for similar structure carries like though primed reference characters corresponding to those of the dispenser or cartridge 15 and the nozzle 21 of FIGS. 15. The dispenser 15' of FIG. 6 differs primarily from the dispenser 15 in that it excludes a second closure, corresponding to the closure 31, and instead the closure 35' is rebent upon itself as indicated best at 42 to define a radially inwardly opening generally annular channel 43. In this manner the peripheral edge portion (unnumbered) ofthe wall 24' is captively though rotatably held between the rebent portion 42 and the oppos ing unnumbered portion of the wall 37'. The nozzle 21 includes a radially offset aperture 23 while the wall 37 includes a like radially offset aperture 34' whereupon rotation imparted to the nozzle 21' relative to the closure 35' results in alignment or misalignment between the apertures 34, 37' thereby respectively permitting and preventing dispensing of material from within the dispenser or cartridge 15.

Another novel dispenser or cartridge 15" is best shown in FIGS. 7-9 and like components have reference numerals corresponding to those of the dispensing mechanism 10 except the same have been double primed. In this case the nozzle 21 is of a two-part threaded assembly including a nozzle component 45 and a dispensing component 46 which includes a cylinan outermost annular wall 56, and a wall 57 therebetween. With the components in the position shown in FIGS. 7 and 8 material will move from the interior of the cartridge 15" in the direction of the unnumbered headed arrows, namely, through the aperture 51 and the aperture 48 into the nozzle 21' and subsequently outwardly thereform upon the removal of the portion 22". However, upon rotation of the nozzle 21" to the position shown in FIG. 9 the wall 57 overlies the aperture 51 whereas the wall 55 overlies and thus closes the aperture 48. In this position the interior of the cartridge 15" is no longer exposed to atmosphere and dispensing is precluded.

A final dispenser or dispensing cartridge 15" is best illustrated in FIGS. -12 of the drawings and components similar to those of the cartridge have'like reference numerals except being triple primed. In the case ofthe cartridge 15" the same includes a pair of closures 33" and 35" with the latter having an aperture 36" through which projects the nozzle 21. A portion of the wall 37" adjacent the aperture 36" is offset and sandwiches a peripheral edge portion (unnumbered) of the nozzle wall 24" in conjunction with the wall 33''. In this manner the nozzle 21" is incapable of axial movement but is free to rotate relative to the closures 33" and 35".

Referring particularly to FIGS. 10 and 12, the wall 33" includes a central embossment 60 formed by a blind circular end wall 61 and a peripheral wall 62 which includes a plurality of radial openings 63. When the nozzle 21 is rotated so that the radial apertures 63 and the passages 64 are not aligned the closure is in a non-dispensing position. In the dispensing position (FIGS. 10 and 12) the apertures 63 aligned with apertures or passages 64 formed by wall portions 65 of the nozzle 21" offset radially outwardly from the wall 62 and slightly axially away from the end wall 61. Thus as material is dispensed from the cartridge 15" it first flows radially outwardly through the apertures 63, thereafter axially and to the left through the passages 64, as viewed in FIG. 10, thus slightly inwardly and finally axially through the opening formed upon the removal of the tip 22".

While preferred forms and arrangements of parts have been shown in illustrating the invention, it is to be clearly understood that various changes in detail and arrangement of parts may be made without departing from the spirit and scope of this invention.
